Ok, now we're on the same page.
OP, here's my 2c
i'd say to with a kingston ssdnow v+100 FTW!
you will get absolute compatibility with every mac / os x version of past, present & future (controller is the same as apple branded ssd's, just a tiny bit less optimized from what someone says), serious trim support which just works and a better bang for the buck.
yeh, your boot time will be 1 (ONE) second higher than III gen ssd's, no biggie to me.
